DLPs E100 to E199

Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms

do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.

Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's

path protection feature, which may be used in any topological network configuration. Cisco does not

recommend using its path protection feature in any particular topological network configuration.

DLP-E100 Initiate a Force Switch on a Port in a 1+1 Protection Group

Step 1 In node view, click the Maintenance > Protection tabs.

Step 2 In the Protection Group area, select the protection group with the port you want to switch.

In the Selected Group area, each port is identified as Working or Protect. Each port also has a status:

• Active—The port is carrying traffic.

• Standby—The port is not carrying traffic.

• [MANUAL TO WORKING]—A Manual switch has moved traffic to the working port.

• [MANUAL TO PROTECT]—A Manual switch has moved traffic to the protect port.

• [FORCE TO WORKING]—A Force switch has moved traffic to the working port.

• [FORCE TO PROTECT]—A Force switch has moved traffic to the protect port.

The normal status is for one port to be Working/Active and the other to be Protect/Standby.

Step 3 In the Selected Group area, select the port that you want to switch. For example, if you want to switch

traffic from the working port to the protect port, click the working port.

Step 4 Click Force.

Purpose This task applies the Force external switching command to a 1+1

protection scheme.

Chapter 17 DLPs E100 to E199

DLP- E101 Apply a Lock On in a 1+1 Group

If the Force switch is successful, CTC shows both ports as [FORCE TO PROTECT] (or

[FORCE TO WORKING]). This indication is shown whether or not the ONS 15600 system has been

able to move traffic from one port to the other.

If the Bidirectional switching check box is checked, both the near-end and far-end nodes switch to the

designated protection ports. For example, if the near-end node has a loss of signal (LOS), it switches to

the protection port and transmits a switch request to the far-end node to switch to the protection port also.

This ensures that both nodes process traffic from the same span.

If the Bidirectional switching check box is not selected, the near-end and far-end nodes switch

independently of each other. For example, if the near-end node has an LOS on its working port, it

switches to the protection port. If the far-end node does not have a LOS, traffic remains on the working

port.

If the Force switch is unsuccessful, clear the switch immediately using the “DLP-E167 Clear a Manual

or Force Switch in a 1+1 Protection Group” task on page 17-53, and then troubleshoot the problems

preventing the switch by referring to the Cisco ONS 15600 Troubleshooting Guide.

Step 5 Click the Conditions tab and click Retrieve to see new events. The switch procedure raises a

FORCED-REQ-SPAN condition that is visible in the window unless Not Alarmed conditions have been

filtered out from the view.

Step 6 Click the Alarms tab.

No new traffic loss alarms or failure-to-switch alarms should appear.

Step 7 Return to your originating procedure (NTP).

DLP-E101 Apply a Lock On in a 1+1 Group

Note A lock on can be applied to a working port only.

Step 1 In node view, click the Maintenance > Protection tabs.

Step 2 In the Protection Groups area, select the protection group where you want to apply a lock on.

Step 3 If you determine that the protect port is in standby and you want to apply the lock on to the protect port,

make the protect port active:

a. In the Selected Group field, click the protect port.

b. In the Switch Commands field, click Force.

Step 4 In the Selected Group area, choose the active port where you want to lock on traffic.

Step 5 In the Inhibit Switching field, click Lock On.

Purpose This task locks traffic onto a working port to prevent traffic from

switching to the protect port in a protection group.

Step 1 Determine the proper location of your bay:

a. For a 900-mm (35.4-inch) wide bay, position the floor template so that corner indicators “B” fall

where you want the corners of the bay to reside (Figure 17-1).

b. For a 600-mm (23.6-inch) wide bay, position the floor template so that corner indicators “A” fall

where you want the corners of the bay to reside (Figure 17-1).

Note If space allows, Cisco recommends you reserve an additional 1/4 inch (6.35 mm) of space

on each side of the bay assembly you are installing.

Purpose This procedure describes how to use the floor template to locate and drill

the appropriate holes that are needed to anchor and provide additional

access to the bay assembly at your site.

Step 1 In node view, click the Provisioning > Comm Channels > SDCC tabs.

Step 2 In the SDCC Terminations area, click Create.

Step 3 In the Create SDCC Terminations dialog box, click the ports where you want to create the DCC

termination. To select more than one port, press the Shift key or the Ctrl key.

Note SDCC refers to the Section DCC, which is used for ONS 15600 DCC terminations. You can

provision the SONET Line DCCs and SDCCs (when not used as a DCC termination by the

ONS 15600) as DCC tunnels. See the “DLP-E105 Create a DCC Tunnel” task on page 17-5. You

can provision SDCC and Line DCC on the same port but it is not recommend. SDCC and Line

DCC are only needed on the same port during a software upgrade if the software version does

not support SDCC. Provision Line DCC termination on the port that already has SDCC see

“DLP-E189 Provision Line DCC Terminations” task on page 17-70. Delete SDCC provisioned

on that port, see “DLP-E198 Delete a Section DCC Termination” task on page 17-76. Enable

OSPF on the Line DCC termination if not enabled see “DLP-E197 Change a Line DCC

Termination” task on page 17-75.

Step 4 In the Port Admin State area, click Set to IS to put the port in service.

Step 5 Verify that the Disable OSPF on SDCC Link is unchecked.

Step 6 If the SDCC termination is to include a non-ONS node, check the Far End is Foreign check box. This

automatically sets the far-end node IP address to 0.0.0.0, which means that any address can be specified

by the far end. To change the default to a specific the IP address, see the “DLP-E196 Change a Section

DCC Termination” task on page 17-75.

Step 7 In the Layer 3 box, perform one of the following:

• Check the IP box only—if the SDCC is between the ONS 15600 and another ONS node and only

ONS nodes reside on the network. The SDCC will use PPP (point-to-point protocol).

• Check the IP and OSI boxes—if the SDCC is between the ONS 15600 and another ONS node and

third party NEs that use the Open System Interconnection (OSI) protocol stack are on the same

network. The SDCC will use PPP.

• Check OSI box only—if the SDCC is between an ONS node and a third party NE that uses the OSI

protocol stack. The SDCC will use the LAP-D protocol.

Note If OSI is checked and IP is not checked (LAP-D), no network connections will appear in

network view.

Purpose This task creates SONET Section DCC terminations required for alarms,

administration data, signal control information, and messages.

DLP- E114 Provision Section DCC Terminations

Step 8 If you checked OSI, complete the following steps. If you checked IP only, continue with Step 9.

a. Click Next.

b. Provision the following fields:

–

Router—Choose the OSI router.

–

ESH—Sets the End System Hello (ESH) propagation frequency. End system NEs transmit

ESHs to inform other ESs and ISs about the NSAPs it serves. The default is 10 seconds. The

range is 10 to 1000 seconds.

–

ISH—Sets the Intermediate System Hello (ISH) PDU propagation frequency. Intermediate

system NEs send ISHs to other ESs and ISs to inform them about the IS NETs it serves. The

default is 10 seconds. The range is 10 to 1000 seconds.

–

IIH—Sets the Intermediate System to Intermediate System Hello (IIH) PDU propagation

frequency. The IS-IS Hello PDUs establish and maintain adjacencies between ISs. The default

is 3 seconds. The range is 1 to 600 seconds.

–

IS-IS Cost—Sets the cost for sending packets on the LAN subnet. The IS-IS protocol uses the

cost to calculate the shortest routing path. The default metric cost for LAN subnets is 20. It

normally should not be changed.

–

Default button—If clicked, sets the default values for the Router, ESH, ISH, IIH, and IS-IS Cost

fields.

c. If the OSI and IP boxes are checked, continue with Step 9. If only the OSI is checked, click Next

and provision the following fields:

–

Mode

AITS—(Acknowledged Information Transfer Service) (Default) Does not exchange data until

a logical connection between two LAP-D users is established. This service provides reliable

data transfer, flow control, and error control mechanisms.

UITS—(Unacknowledged Information Transfer Service) Transfers frames containing user data

with no acknowledgement. The service does not guarantee that the data presented by one user

will be delivered to another user, nor does it inform the user if the delivery attempt fails. It does

not provide any flow control or error control mechanisms.

–

Role—Set to the opposite of the mode of the NE at the other end of the SDCC.

–

MTU (Maximum transmission unit)—Sets the maximum number of octets in a LAP-D

information frame. The range is 512 to 1500 octets. The default is 512. You normally should not

change it.

–

T200— Sets the time between Set Asynchronous Balanced Mode (SABME) frame

retransmissions. The default is 0.2 seconds. The range is 0.2 to 20 seconds.

–

T203—Provisions the maximum time between frame exchanges, that is, the trigger for

transmission of the LAP-D “keep-alive” Receive Ready (RR) frames. The default is 10 seconds.

The range is 4 to 120 seconds.

Step 9 Click Finish.

Step 10 Return to your originating procedure (NTP).

DLP- E115 Change the Service State for a Port

DLP-E115 Change the Service State for a Port

Step 1 In node view, double-click the card with the port(s) you want to put in or out of service. The card view

appears.

Step 2 Click the Provisioning > Line tabs.

Step 3 In the Admin State column for the target port, choose one of the following from the drop-down list:

• IS—Puts the port in the In-Service and Normal (IS-NR) service state.

• OOS, DSBLD—Puts the port in the Out-of-Service and Management, Disabled (OOS-MA,DSBLD)

service state. In this service state, traffic is not passed on the port until the service state is changed

to IS-NR; Out-of-Service and Management, Maintenance (OOS-MA,MT); or Out-of-Service and

Autonomous, Automatic In-Service (OOS-AU,AINS).

• OOS, MT—Puts the port in the OOS-MA,MT service state. This service state does not interrupt

traffic flow and loopbacks are allowed, but alarm reporting is suppressed. Raised fault conditions,

whether or not their alarms are reported, can be retrieved on the CTC Conditions tab or by using the

TL1 RTRV-COND command. Use the OOS-MA,MT service state for testing or to suppress alarms

temporarily. Change to the IS-NR or OOS-AU,AINS service states when testing is complete.

• IS, AINS—Puts the port in the OOS-AU,AINS service state. In this service state, alarm reporting is

suppressed, but traffic is carried and loopbacks are allowed. After the soak period passes, the port

changes to IS-NR. Raised fault conditions, whether their alarms are reported or not, can be retrieved

on the CTC Conditions tab or by using the TL1 RTRV-COND command.

Note CTC will not allow you to change a port service state from IS-NR to OOS-MA,DSBLD. You

must first change a port to the OOS-MA,MT service state before putting it in the

OOS-MA,DSBLD service state.

For more information about service states, refer to the “Administrative and Service States” appendix of

the Cisco ONS 15600 Reference Manual.

Step 4 If the port is in loopback (OOS-MA,LPBK & MT) and you set the Admin State to IS, a confirmation

window appears indicating that the loopback will be released and that the action could be service

affecting. To continue, click Ye s .

Step 5 If you set the Admin State to IS,AINS, set the soak period time in the AINS Soak field. This is the

amount of time that the port will stay in the OOS-AU,AINS service state after a signal is continuously

received. When the soak period elapses, the port changes to the IS-NR service state.

Step 6 Click Apply.

Step 7 As needed, repeat this task for each port.

Purpose This task puts a port in service or removes a port from service.
